They Say What They Say

I was reading something somewhere that there are degrees of natural 'handness' as is were. Most people have varying degrees of preference toward one of the other, with some people going more or less totally one way, while others fall somewhere in the middle. I do a lot of things with my left hand that I can't do with my right so I count myself as fairly ambidextrous, whereas my niece is so left handed her right hand might as well not exist!
